I also see it as a position I wouldn't want in a million years, but whenever I talk to salespeople I can absolutely see why they do it. There seems to be a mindset, or a particular kind of motivation, that fits with the act of selling and with the idea of commission based earnings. I'm also not sure that many salespeople see their role as "sell whatever the company makes". There's a common trope of engineers scrambling to build what the sales team have sold, but even aside from that, I think many salespeople see their job as building and growing accounts in their clients, and finding the products or features available to grow into. Perhaps just a perspective difference, but that can be all that matters.
